This is optional to enable the **Digital River Service Checker** and **Request SKUs** to update the modules. In Business Manager, select **Administration**, and then select **Roles and Permissions**. To add the Digital River modules to a role, click the role you want to modify (or create a new one). Then click one or more checkboxes to select the **Business Manager** modules for that role.
In the next menu, add the **Write** permission to the Digital River group as indicated below.
See [Business Manager](#business-manager) for more information about Digital River modules. Lastly, the order status update job must be able to access the order to update the status of the order properly. To enable this job to function properly, you must change the site settings. 1. Select **Merchant Tools**, select **Site Preferences**, and click **Order**. 2. Set **Limit Storefront Order Access** to **No**. 3. Set **Storefront Order Filter by Customer Session** to **No**.
## Updating shipping methods to support digital products In order to meet the SFCC requirement to have a shipping method for creating an order, add a dedicated digital shipping method for digital products with a specified price amount. Set the **Exclusions** of the shipping method (as shown below).
Ensure that if the basket contains the products without the custom attribute`drDigitalProduct`and products where that attribute is set to`false`, this digital shipping method will not be applicable. Therefore, customers are unable to select this shipping method for mixed and non-digital carts. {% hint style="info" %} **Note**: All other existing shipping methods should be also configured so that they are not shown when there are only digital products in the basket. {% endhint %}
